2 📊 Survey Results
Each item was rated on a 7-point scale from the left concept to the right. Lower values indicate stronger agreement with the first term (e.g., ‘Annoying’), while higher values reflect stronger agreement with the second (e.g., ‘Enjoyable’).

3 💹 Scale structure of the UEQ
4 ⏰ By Period
We used an ordinal logistic regression model to account for the ordered nature of the response scale. This allowed us to estimate the likelihood of each response level across time periods or experience in VHF response and visualize these shifts using the predicted probability plot.
4.1 📈 Attractiveness
Significance of Period Effect
Observed Response
Annoying – Enjoyable
Not understandable – Understandable
Good – Bad
Unlikable – Pleasing
Unpleasant – Pleasant
Attractive – Unattractive
